Because the pieces have to be precisely the correct "LENGTH" sanding
will
almost always change the length of the piece of wood.


Just a comment, It does not matter how close to perfection the miter cut
is, if the opposite sides of the frame are not absolutely the same
length the miter is not perfect.

This is another place where the shooting board is handy... if pieces aren't
exactly the same length, or not perfectly straight, the miters can be
adjusted by using paper shims to adjust the position of the stock on the
shooting board.

I posted a couple photos of cutting and shooting miters on ABPW that show
how a shooting board would be used for this purpose.
